RRNAA Superior Phylogenetic Marker

Comparative ribosomal RNA (rRNA) sequence analysis has become a widely accepted method for establishing phylogenetic relationships between bacterial species, and rRNA sequence information has become a well-established method for microbial identification.1-8-1

rRNA sequence differences between closely related species enable the design of species-specific probes targeting almost any microorganism. Such probes are obvious reagents for microbial identification and enable diagnostic microbiology to be based on a single genetic marker rather than a series of biochemical tests.

Prepare blood culture smear with 1 drop of Fixation

Add 1 drop of PNA probe

Incubate for 90 min. at 55°C

Immerse slide in Wash Solution for 30 min. at 55°C

Add 1 drop of Mounting Medium

Getting Started With Dumbbells

The use of dumbbells gives you a much more comprehensive strengthening effect because the workout engages your stabilizer muscles, in addition to the muscle you may be pin-pointing. Without all of the belts and artificial stabilizers of a machine, you also engage your core muscles, which are your body's natural stabilizers.
